Bug Description
Whenever we use Fanotify to monitor "CIFS" mounted volumes and
try to write to a new file by doing:
echo "ABC" > /mnt/cifs/test.c
It takes around 10-15 secs to complete the write operation.
This happens only when we try to monitor "FAN_OPEN_PERM". Looks like "FAN_OPEN_PERM" blocks and notifies only after 10-15 secs.
